2017-04-27Merge branch 'qed-ptp-enhancements'David S. Miller
Sudarsana Reddy Kalluru says: ==================== qed*: PTP enhancements. The patch series contains set of enhancements for qed/qede ptp implementation. Patches (1)-(3) adds resource locking implementation to allow PTP functionality only on the first detected ethernet PF of the port. The change is required as the adapter currently supports only one instance of the PTP client on a given port. Patch (4) removes the un-needed header file. Patch (5) moves the ptt-lock get/release logic to the ptp specific code. Please consider applying this series to "net-next" branch. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2017-04-27qede: Add support for PTP resource locking.sudarsana.kalluru@cavium.com
The patch adds necessary changes to the driver to use qed resource locking functionality. Currently the ptp initialization is spread between driver probe/open implementations, associated APIs are qede_ptp_register_phc()/qede_ptp_start(). Clubbed this functionality into single API qed_ptp_enable() to simplify the usage of qed resource locking implementation. The new API will be invoked in the probe path. Similarly the ptp clean-up code is moved to qede_ptp_disable() which gets invoked in the driver unload path.

2017-04-27qed: Add support for PTP resource locking.sudarsana.kalluru@cavium.com
The patch adds support for per-port resource lock in favour of PTP. PTP module acquires/releases the MFW resource lock while enabling/ disabling the PTP on the interface. The PF instance which has the ownership of this resource lock will get the exclusive access to the PTP clock functionality on the port.

2017-04-27bridge: add per-port broadcast flood flagMike Manning
Support for l2 multicast flood control was added in commit b6cb5ac8331b ("net: bridge: add per-port multicast flood flag"). It allows broadcast as it was introduced specifically for unknown multicast flood control. But as broadcast is a special case of multicast, this may also need to be disabled. For this purpose, introduce a flag to disable the flooding of received l2 broadcasts. This approach is backwards compatible and provides flexibility in filtering for the desired packet types.

2017-04-27dm ioctl: prevent stack leak in dm ioctl callAdrian Salido
When calling a dm ioctl that doesn't process any data (IOCTL_FLAGS_NO_PARAMS), the contents of the data field in struct dm_ioctl are left initialized. Current code is incorrectly extending the size of data copied back to user, causing the contents of kernel stack to be leaked to user. Fix by only copying contents before data and allow the functions processing the ioctl to override.

The change in commit 1e2f82d1e9d1 ("statx: Kill fd-with-NULL-path support in favour of AT_EMPTY_PATH") to error on a NULL pathname to statx() is inconsistent. It results in the error EINVAL for a NULL pathname. Other system calls with similar APIs (fchownat(), fstatat(), linkat()), return EFAULT. The solution is simply to remove the EINVAL check. As I already pointed out in [1], user_path_at*() and filename_lookup() will handle the NULL pathname as per the other APIs, to correctly produce the error EFAULT.

2017-04-27rhashtable: Cap total number of entries to 2^31Herbert Xu
When max_size is not set or if it set to a sufficiently large value, the nelems counter can overflow. This would cause havoc with the automatic shrinking as it would then attempt to fit a huge number of entries into a tiny hash table. This patch fixes this by adding max_elems to struct rhashtable to cap the number of elements. This is set to 2^31 as nelems is not a precise count. This is sufficiently smaller than UINT_MAX that it should be safe. When max_size is set max_elems will be lowered to at most twice max_size as is the status quo.
